Request OEM unlock Huawei P10

Hi all,
I have an incorrect firmware installed for my P10 and lots of things are not working (oreo 8.0). I want to re-flash or rollback to other firmwares but problem is I can't get into TWRP anymore. flashing it doesn't work and although I see in fastboot Phone Unlocked and FRP unlock i have the idea it has to do with the OEM unlock not working properly. It's also not available in the developer options. What;s exactly the link to huawei's page where you can request your phone unlock ID ?
Thanks

Whats not working ?
What is it saying when flashing something through fastboot ?

First of all, I've tried to update from Nougat to Orea via Blackballs method in this thread https://forum.xda-developers.com/p10-plus/development/oreo-update-thread-l29c432-t3729907 with the firmware mentioned there
What is not working:
I've managed to do the first part (oreo install), but:
- SImcard has 'No service
- Can't flash TWRP
- Bootloader / phone locked in Fastboot
- I can't remember how I unlocked the P10 last year (I have a P10 L09-VTR, rebranded to L29-VTR and now 'working' on a VKY P10 plus rom)

Help!!, frp locked bootloader locked

So what happend is i wanted to get oreo on my pra la1 so i re branded it to al00c chinese version (after unlocking my bootloader)
using the al00c oem file , i flash d it in twrp and then i wanted google play services which is not there in chinese version so i unlocked bootloader again and flashed oreo twrp and then flashed pra lx1 oem info and i did not dload the lx1 software:crying: so stupid of me now i m running chinese software on lx1 and without google play now my frp and bootloader is locked. now when i try dload it goes to 5% and says system update failed . WHAT DO I DO NOW TO GET PRA LX1C432 OREO??
THANX IN ADVANCE

Try Firmware finder for huawei + erecovery method , which is :
- download firmware finder on *another android phone* and search for exact phone model (ex : PRA-LA1C185)
- choose the very first firmware down the list
- Get an update thorugh dns >> Manually >> Register update
- After that , reboot your bricked phone into erecovery by ( power + volume*+*)
- press download recovery and last firmware
- wait till getting package
- by now should firmware start downloading
- let phone complete it's work and reboot
Hope that's work for you ?

I have the bootloader unlocked via DC Unlocker. Must pay 3,99€ because it's okay.
NOW: I want flash twrp via adb-fastboot and it comes

Try this:
fastboot flash recovery xxx(name of recovery).IMG.
It's the old nougat command. Might work. Depends on what partition scheme your device has. Give it a shot. Likely won't but you can try.

Got same issue yesterday. After some i got a length partition issue.
I did the full OTA from eRecovery. Now i'm on PRA-LX1 8.0.0.368 C02 (NOT C432).
I should try again (i believe my device is now totally stable - i think i flashed bad rom with HuRUpdater...) and see if i can flash a TWRP (certainly 3.2.1 Oreo) with fastboot flash recovery_ramdisk twrpfile.img
Will let you know.

How can be helped if not provided which ROM you had (full build model, cust nunber), what you did (wrong), and such details - bootloader unlocked, TWRP installed, etc?
What is 'rescue' mode - you mean Recovery (or eRecovery)?

MM, N and O (corresponding EMUI version) each has different organization of partitions (O even differently named two partitions) and different encryption of Data and Internal mem
Flashing wrong TWRP causes brick (even worse if you then proceeded by DLOAD or something with that inappropriate TWRP

TWRP for Huawei directly from their site is (maybe) good for Huawei MM but not for N or O
Use only 3.1.1-1 'endorsed' for Huawei Nougat !!! from

Try if you can unbrick by flashing proper TWRP fron Fastboot and by DLOAD afterwards.
If you need, download corresponding (must be FullOTA) update.zip from Firmware Finder (it's possible from PC since your P9 does not boot or use any other Android phone), unzip, use Huawei Update Extractor (PC app, search on XDA for) to extract Recovery.img

In the Fastboot mode, are both Phone (=Bootloader) and FRP red, showing Unlocked?
If not, you can not flash anything

That is the problem - to flash you need both Bootloader and FRP unlocked but with wrong TWRP or so, you locked FRP
To unlock FRP you would need to boot to System and check OEM Unlock under Developer Options - but if you ccannot boot to System, it is bricked
IMO, no other way now but to buy 15 EUR credit for DC Phoenix, they can unlock (TG, I didn't need to use DC Phoenix , hence cannot help about, you can ask them over their page)
https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
You can also search here on XDA, there were other users who un-bricked by their tool, if I recall there was also somebody with a similar brick: FRP locked but cannot boot to System

Custom ROM / TWRP for Honor 10 Lite?

Hey guys,
I just bought the Honor 10 lite and I am not really a big fan of Huawei's EMUI. That's why I wondered if there is already any custom ROM somewhere out there for this phone? I know it's pretty new and I couldn't find anything so far..
Would still appreciate any information, if somebody knows more about it.
Thanks guys :highfive:

You need to unlock bootloader 1st and that's currently impossible for honor 10 lite with Android 9
Even paid service isn't an option.

Oh alright, forgot that they stopped providing unlock-code's.. Hope someone figures out something, still not a friend of EMUI.
Thanks for the reply man ?

I just noticed that with the latest fw update as of today (9.0.1.142), the OEM unlock option can be now changed from the developer options menu, I guess it is still impossible to unlock it but well, now at least it lets you to change the option (before the update it wasn't even possible to do so). I'm not now able to but someone should give it a try to see if by any chance they messed up with OEM...

I think we'll have to wait many months before someone finds an hack to unlock bootloader. This is a very recent smartphone and also Huawei and Honor are not for modding, since it's everything locked and they're not providing unlock codes anymore. Too bad I discovered it after I bought it !

How did you unlock the bootloader?
To install magisk you need to install twrp first, then flash magisk zip from there. But there's no twrp for our device so far, maybe you can try running a twrp of a device with our same socket without installing it, from fastboot, and see if it works. For example
Code:
fastboot boot twrpfilename.img
If it works, then you can try flashing magisk from there.

Bootloader is locked and you can't flash anything till it's locked. There are paid services to unlock it but so far our device is not supported. Though there's no sense to pay a lot of money to unlock it, also if it was supported, just to have root (if you're lucky) , since there are no custom ROMs for Honor 10 lite. Our device is not made for modding. The only solution on my opinion is to wait patiently till someone finds an hack to unlock it for free, or sell your phone and buy a Xiaomi. You can unlock bootloader very easily and there are plenty of custom ROMs for it.

Just make sure it's really a complete service ROM.

Don't have a google search?
- Unpack archive
- Copy dload folder (without unpacking it !) to the root of your SD Card
- Turn off the phone
- Press and hold Power and both Volume buttons ("three button combo" method).

Choose one and follow the instructions .
P.S .: you can install any GSI Custom from the section Huawei P20 lite, Honor 9 lite and P20 lite are basically the same phones.
(EMUI 9.1 is required).

@mbook12 Any roms I try to download there I only get an ad for an iphone... Any idea where I can get a lld-l21 EMUI 9.1 firmware? Any attempts to update mine (with EMUI 8.0) it always claims to be at the latest version.

I think it's 432 - but now I've realized I have more issues, as I can't find it in the "About phone" and the model shows "unknown" instead of lld-l21.

L21 C432 doesn't exist.
In fastboot mode run commands (use "Minimal ADB and fastboot" tool on PC) :
fastboot oem get-build-number
fastboot oem get-product-model
fastboot getvar vendorcountry
fastboot oem oeminforead-CUSTOM_VERSION
fastboot oem oeminforead-SYSTEM_VERSION
and post the results.
Some might fail, so don't worry about it.

Thanks, I'm on linux so it is a different package to install fastboot and adb. Anyway, the results are more worrying:
Code:
$ fastboot oem get-build-number
(bootloader) :System 8.0.0.046(06HJ)
OKAY [ 0.005s]
Finished. Total time: 0.005s
$ fastboot oem get-product-model
(bootloader)
OKAY [ 0.005s]
Finished. Total time: 0.005s
$ fastboot getvar vendorcountry
getvar:vendorcountry FAILED (remote: 'cannot get vendorcountry in oeminfo')
Finished. Total time: 0.009s
$ fastboot oem oeminforead-CUSTOM_VERSION
FAILED (remote: 'The reason of failed input oem_nv_item error!')
fastboot: error: Command failed
$ fastboot oem oeminforead-SYSTEM_VERSION
FAILED (remote: 'Read oeminfo failed!')
fastboot: error: Command failed
Seems I have lost all oeminfo.
Seems like it is time for the full background story - I had managed to unlock the bootloader using the PotatoNV/testpoint method. Unfortunately, flashing the official AOSP I was dumb enough to forget I had emui 8 and flashed also the Phenix kernel. That broke all - no more TWRP, fastboot reflashing the stock erecovery, recovery_ramdisk, etc. didn't work, flashing stock kernel got it back to booting into erecovery or TWRP. Attempts to flash system ended always with error after it sent the first segment of the sparse file, so on recommendation of a fellow xda'er I used the Huawei Flash Tools IDT 2.0 and the only xml firmware file I could find for the lld-l21 - Huawei_Honor_9_Lite_LLD-L21_1.0.0.42_Board_Software_General_8.0.0_R1_EMUI_8.0_05022GGQ_HMT.zip
After that booted into (I think) factory mode, I did the update with the sdcard dload mode, using LLD-L21A 8.0.0.122(C636) Honor 9 Lite_Firmware_Android8.0.0_EMUI8.0.0_05014XCA_DA_romadd.com.zip
So, my lld-l21 should be now on region 636, but apparently is on none.
